Step 1Prep the zucchini: Shred the zucchini and squeeze out as much liquid as possible using a clean kitchen towel.
Step 2Make the crust: In a bowl, mix zucchini, egg, flour, shredded cheese, Parmesan, garlic powder, and salt until thick and sticky.
Step 3Form the base: Spread the mixture onto a parchment-lined baking sheet into a 10–12 inch circle, about ¼-inch thick.
Step 4Bake the crust: Bake at 450°F for 10–12 minutes, until firm and lightly golden.
Step 5Add toppings: Spread tomato sauce over the crust, sprinkle with cheese, and add desired toppings.
Step 6Bake again: Return to the oven for 5–7 minutes, until the cheese is melted and bubbly.
Step 7Cool & serve: Let cool slightly before slicing and serving.
